Note: These tubes have not been tested. The in-box tubes appear new in box. They came from a large collection of tubes from which the collector marked most broken tubes with an X. Sold as is, untested. This mixed lot of 11 tubes includes varieties of 12AX7A, 12AT7WB, 12AX7, and 12AT7 types made by trusted brands such as Sylvania, RCA, and GE. The Sylvania tubes appear to be “new old stock”. Two of the GE tubes (the 12At7 and 12AT7wb) are loose. The rest seem to be NOS as well.
